Here’s a riddle for you. I want to feel like a sultan, but I don’t want to spend a lot of money. I’m thinking, like, zero to one dollars. Impossible, right? WRONG. Nothing is impossible. We put a robot on Mars, for crying out loud. Granted, it’s really just a glorified vacuum cleaner that sucks up rock samples, but it does have its own Twitter account, so, you know…that’s pretty amazing. Back to discount sultan role play. One of the best things about the city of Boston, besides the inexplicably large inventory of water fowl themed boats, is the fleet of pedicabs that roams the streets. For the uninitiated, a pedicab is a human powered conveyance that looks like a bicycle on steroids. Ironically, you have to be on steroids to drive one, because passenger loads can total upwards of 500 pounds. That translates to about three people, if you are in the theater district, or one person, if you are in the North End (it’s not their fault – you gain ten pounds just by walking on Hanover Street). And the craziest part about hiring a fellow human to haul your lazy butt to the ice cream parlor? You pay what you want. That’s right: pedicab operators may only suggest a fare. It’s up to you whether or not you want to honor it. This means that, theoretically, you could get a ride to Logan Airport for one dollar. And you get free entertainment: watching somebody struggle to pedal 500 pounds up a hill. But that’s only if you’re a jerk. Or [cough] a sultan. Taxi!
